摘要
本文研究张掖制种玉米关键生长阶段气象因子适宜指标,确定影响品质的主要气候条件及关键因素,探讨了张掖制种玉米气候品质认证技术。利用张掖国家基准气候站气温、降水、日照等气象资料,分析2020年热量、光照、降水气候条件及诸因子对制种玉米主要生长期的影响,最终对张掖制种玉米进行气候品质等级认证分析评估。结果表明,2020年研究区域温度、日照条件有利于玉米生长发育和品质形成;2020年伏期干旱和病虫害对制种玉米生长发育造成一定影响,种植基地采取相应防范措施减轻危害程度。通过对制种玉米地理产区区划指标、当年制种玉米生长期气候条件、制种基地生产管理情况进行评分,得出认证区域内制种玉米气候品质等级为特优。
In this paper,the meteorological suitability indexes at key growing stages of seed maize in Zhangye were studied,the meteorological conditions and meteorological factors were examined and the climate quality certification technology of seed maize in Zhangye was discussed.Based on the data of air temperature,precipitation,sunshine duration from the Zhangye National Reference Climatological Station,the effects of meteorological factors in 2020,including heat,light,precipitation and etc.,on the growth of seed maize were analyzed,and the assessment of the climate quality grade certification of seed maize in Zhangye was carried out.The results showed that the temperature and sunshine in 2020 were conducive to the growth and quality formation of seed maize;the summer drought and diseases had certain influence on the development of seed maize,and the cultivation base of seed maize should take steps to reduce the hazard degree.According to the geographic regionalization index of seed maize,the climatic conditions of maize growth of the year and the production management of seed maize enterprises,the climate quality grade of seed maize in the certified region is excellent.
